请帮我找出为什么我的背景图像没有显示。 代码确实在web页面上创建了一个div，但是图像只是没有显示出来。 我插入html img标记，看看图像是否工作良好，它确实工作良好，所以我认为这一定是CSS部分出了问题。

这是我的html代码
<section id="experience">
<div class="experience-photo">
</div>
<div class="experience">
<h2>In the process of understanding society</h2>
<div>
<div class="">
<img src="Images /UBC.jpeg" alt="ubc">
</div>
<div class="">
<a href="https://www.ubc.ca/">The University of British Columbia</a>
<h3>B. S. in Sociology with minor in Business, class of 2020</h3>
<h3>Vancouver,Canada</h3>

如果文件夹名称中没有空格，请删除“images/experience.jpg”中图像后面的空格。 肯定会管用的。
